A. Classification errors refer to instances in machine learning where a model incorrectly assigns a data point to the wrong class or category. These errors can be false positives (misclassifying something as belonging to a class when it doesn’t) or false negatives (failing to classify something correctly). zero_division{“warn”, 0.0, 1.0, np.nan}, default=”warn”. Sets the value to return when there is a zero division. If set to “warn”, this acts as 0, but warnings are also raised. New in version 1.3: np.nan option was added. Returns: reportstr or dict.
